AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
201 PM CDT SAT JUN 12 2004

.SHORT TERM...
WATER VAPOR IMAGERY INDICATING SHORTWAVE TROUGH PROGRESSING THROUGH
SOUTH CENTRAL NEW MEXICO EARLY THIS AFTERNOON.  SOME CU/ALTOCU
APPEARING ON VISIBLE IMAGERY...PORTENDING THINGS TO COME.

VERY DRY AIR MIXING DOWN OVER THE WESTERN CWA...SHARPENING AND
PROPAGATING DRYLINE EASTWARD.  THINK THE DRYLINE WILL BE SLIGHTLY
FURTHER WEST THAN MESOETA DEPICTING BY 13/00Z AS WINDS HAVE NOT
VEERED AS MUCH AS EXPECTED.  ATMOSPHERE IS VERY UNSTABLE TO THE EAST
OF THE DRYLINE WITH MUCAPE PROGGED TO BE 1500 TO 2000 J/KG AND LI/S
AROUND -3 C ALONG SAME BY LATE AFTERNOON.  H7 TO H5 LAPSE RATES NEAR
8 C/KM ARE ALSO PROGGED ALONG THE DRYLINE AS MID LEVEL LIFT
INCREASES FROM WEST TO EAST AHEAD OF ONCOMING SHORTWAVE TROUGH.
EXPECT ELEVATED THUNDERSTORMS TO DEVELOP BETWEEN 12/21Z AND 13/00Z
AS ABOVE INSTABILITY/LIFT WILL ACCOMPANIED BY AN 80 KT H25 JET AND
DIFFLUENT FLOW ALOFT.  0 TO 6 KM BULK SHEAR VECTORS PROGGED TO BE 35
TO 40 KT ACROSS THESE AREAS WHILE FORECAST SOUNDINGS INDICATING
INVERTED V CHARACTERISTICS.  WIND AND HAIL WILL INITIALLY BE THE
MAIN THREAT...BUT ISOLATED TORNADOES POSSIBLE AS LOW LEVEL WINDS
BACK LATE THIS AFTERNOON AND EVENING.  IT APPEARS AN MCS WILL FORM
LATER THIS EVENING AS H85 LLJ INCREASES.  LOW LEVEL MOISTURE VERY
PLENTIFUL...SO FLASH FLOODING WILL ALSO BE OF CONCERN MAINLY OVER
THE EASTERNMOST ZONES.

A LITTLE SKEPTICAL OF LOW CLOUDS DEVELOPING OVER THE EAST IN THE
MORNING...BUT SOME LOCATIONS MAY SEE FOG AFTER CLOUDS CLEAR OUT FROM
TSRA.  FORECAST LOWS LOOK GOOD SO LEFT THEM ALONE.  OTHERWISE...
TWEAKED WIND AND DEWPOINT GRIDS.

.LONG TERM...
SHOULD BE A QUIETER DAY SUNDAY AS THE SIGNIFICANT SOUTHERN STREAM
SHORTWAVE MOVES TO THE EAST WITH SUBSIDENCE IN ITS WAKE FOR MUCH OF
THE DAY. DRYLINE WILL MIX TO THE EASTERN PERMIAN BASIN BY LATE
SUNDAY AFTERNOON IN THE NORTHWEST FLOW ALOFT. WILL LEAVE OUT MENTION
OF THUNDER IN ZONES IN THE PERMIAN BASIN WITH SIGNIFICANT MIXING OUT
OF LOW LEVEL MOISTURE AND LACK OF SIGNIFICANT UPPER DISTURBANCE.
WILL LEAVE ISOLATED CONVECTION MENTION IN THE LOWER TRANSPECOS AND
BIG BEND WITH LINGERING INSTABILITY AND OROGRAPHICS THAT COULD AID
IN ANY POSSIBLE INITIATION.

WILL CONTINUE TO CONFINE ISOLATED POPS TO THE LOWER TRANSPECOS AND
BREWSTER COUNTY ON MONDAY AS THIS WILL BE ONLY AREA WHERE ENOUGH
INSTABILITY AND LOW LEVEL CONVERGENCE COEXIST. BY TUESDAY THE LOW
LEVEL MOISTURE WILL BEGIN TO RETROGRADE BACK TOWARD THE HIGHER
TERRAIN OF SOUTHWEST TEXAS AND SOUTHEAST NEW MEXICO COURTESY OF
UPSLOPE FLOW. WILL CONTINUE THE ISOLATED POPS MAINLY SOUTH AND WEST
OF THE PECOS RIVER FOR CONVERGENCE ALONG DRY LINE AND OROGRAPHIC
UPSLOPE FLOW IN THE HIGHER TERRAIN. WEAK FLOW ALOFT WILL NOT BE
FAVORABLE FOR STORMS TO MOVE MUCH EAST INTO THE PERMIAN BASIN.

BY WEDNESDAY THE DISTURBANCE CURRENTLY NEAR THE BAY OF CAMPECHE
MAY BECOME A PLAYER ACROSS THE EXTREME EAST IF IT TRANSLATES AS
FAR WEST AS THE ECMWF DEPICTS. WILL SHOTGUN ISOLATED POPS IN
UPSLOPE FLOW AND SHORTWAVE/SURFACE TROUGH IN THE WEST AND IN
THE EAST DUE TO THE AFOREMENTIONED DISTURBANCE.

AT THIS TIME WILL LEAVE THE WEDNESDAY THROUGH SATURDAY PERIODS ALONE
IN THE DATABASE DEPICTING ISOLATED CONVECTION DUE TO PROXIMITY
AND UNCERTAIN TRACK OF THE GULF DISTURBANCE AND MOIST UPSLOPE FLOW
IN THE WEST/HIGHER TERRAIN. POPS MAY NEED TO BE RAISED FRIDAY AND
SATURDAY AS A NORTHERN STREAM COLD FRONT MAY BE MOVING INTO THE
SOUTHERN PLAINS.
